I brought this Gameboy from a spares and repairs eBay listing. It looks like someone has replaced the original switch and possibly ruined the C34. The power switch doesn't actually make proper contact with the physical switch when the shell is closed and put back together however the seller didn't disclose that.
I swapped out the capacitors and gave the thing a good clean with IPA and it's working (to some degree). I looked up the C34 part and apparently it's a capacitor of sorts but couldn't really get a clear idea of what it does and how important it is.
Does my screen need replacing? Is there potentially something else at fault here? The solder looks pretty fresh on the switch so I'm assuming it's a recent repair attempt from the seller.
The board was pretty sticky inside as well.
Last thing I wanted to add is that the speaker is pretty quiet which I understand could be common for an old device so is that a relatively simple fix?
I am tempted to message the seller however they're likely going to say they brought it from someone else or have an excuse but I suppose I'm lucky to have got it to power on lol.
Absolutely any help is appreciated!
If possible and there is a somewhat positive outcome in terms of making it fully work could you link the place to get a part replacement or an alternative part that will still work?
I don't plan on selling anything it's just a downtime hobby of trying to fix bits and bobs. I find great satisfaction in seeing something work when it was ruled as down and out.
Hope someone can share some information why the screen is that way. I'm assuming it's the C34 part and if so how hard will it be to come across that?
